Buffer objects are cool! This abstracts the buffer API first introduced
by GL_ARB_vertex_buffer_object and then extended to other objects.
The coglBuffer abstract class is intended to be the base class of all
the buffer objects, letting the user map() buffers. If the underlying
implementation does not support buffer objects (or only support VBO but
not FBO for instance), fallback paths should be provided.

ClutterAnimator is a class for managing the animation of multiple
properties of multiple actors over time with keyframing of values.
The Animator class is meant to be used to effectively describe
animations using the ClutterScript definition format, and to construct
complex implicit animations from the ground up.

This adds three new texture backends.
- CoglTexture2D: This is a trimmed down version of CoglTexture2DSliced
which only supports a single texture and only works with the
GL_TEXTURE_2D target. The code is a lot simpler so it has a less
overheads than dealing with slices. Cogl will use this wherever
possible.
- CoglSubTexture: This is used to get a CoglHandle to represent a
subregion of another texture. The texture can be used as if it was a
standalone texture but it does not need to copy the resources.
- CoglAtlasTexture: This collects RGB and RGBA textures into a single
GL texture with the aim of reducing texture state changes and
increasing batching. The backend will try to manage the atlas and
may move the textures around to close gaps in the texture. By
default all textures will be placed in the atlas.
High level toolkits might wish to construct a PangoFontDescription and
then set it directly on a ClutterText actor proxy or sub-class.
ClutterText should have a :font-description property to set (and get)
the PangoFontDescription.

In the example for clutter_actor_animate the "x" and "y" properties
are floats so they need to be passed float values in the var args
otherwise it will crash. There was also a missing comma.
There were some other minor problems with the behaviours example which
would cause it not to compile.
An example of what could be the equivalent of
"RBG = REPLACE(TEXTURE)
A = MODULATE(PREVIOUS,TEXTURE)"
using the ARB_texture_env_combine extension was given, but it seems that
a few typo were left:
* remove a spurius GL_COMBINE_ALPHA
* use the _ALPHA variant of SRCN and OPERANDN when setting up the
alpha combiner
Allow the user of the ClutterMedia interface to specify a Pango font
description to display subtitles. Even if the underlying implementation
of the interface does not natively use Pange, it must be capable of
parsing the grammar that pango_font_description_from_string() accepts.
Since asking for ARGB by default is still somewhat experimental on X11
and not every toolkit or complex widgets (like WebKit) still do not like
dealing with ARGB visuals, we should switch back to RGB by default - now
that at least we know it works.
For applications (and toolkit integration libraries) that want to enable
the ClutterStage:use-alpha property there is a new function:
void clutter_x11_set_use_argb_visual (gboolean use_argb);
which needs to be called before clutter_init().
The CLUTTER_DISABLE_ARGB_VISUAL environment variable can still be used
to force this value off at run-time.
At first, those symbols were called {get,set}_subtitles_uri() but were
renamed to {get,set}_subtitle_uri() without updating the
clutter-section.txt file.
This fix makes gtk-doc document those symbols again.
Allow the user of the ClutterMedia interface to specify an external (as
in not multiplexed with the audio/video streams) location of a subtitle
stream.

ClutterActor checks, when destroying and reparenting, if the parent
actor implements the Container interface, and automatically calls the
remove() method to perform a clean removal.
Actors implementing Container, though, might have internal children;
that is, children that are not added through the Container API. It is
already possible to iterate through them using the Container API to
avoid breaking invariants - but calling clutter_actor_destroy() on
these children (even from the Container implementation, and thus outside
of Clutter's control) will either lead to leaks or to segmentation
faults.
Clutter needs a way to distinguish a clutter_actor_set_parent() done on
an internal child from one done on a "public" child; for this reason, a
push/pop pair of functions should be available to Actor implementations
to mark the section where they wish to add internal children:
➔ clutter_actor_push_internal ();
...
clutter_actor_set_parent (child1, parent);
clutter_actor_set_parent (child2, parent);
...
➔ clutter_actor_pop_internal ();
The set_parent() call will automatically set the newly added
INTERNAL_CHILD private flag on each child, and both
clutter_actor_destroy() and clutter_actor_unparent() will check for the
flag before deciding whether to call the Container's remove method.
ClutterLayoutManager does not have any state associated with it, and
defers all the state to its sub-classes.
The BoxLayout is thus in charge of controlling:
• whether or not animations should be used
• the duration of the animation
• the easing mode of the animation
By adding three new properties:
• ClutterBoxLayout:use-animations
• ClutterBoxLayout:easing-duration
• ClutterBoxLayout:easing-mode
And their relative accessors pairs we can make BoxLayout decide whether
or not, and with which parameters, call the begin_animation() method of
ClutterLayoutManager.
The test-box-layout has been modified to reflect this new functionality,
by checking the key-press event for the 'a' key symbol to toggle the use
of animations.
In order to animate a fluid layout we cannot use the common animation
code paths as they will override the size request and allocation paths
that are handled by the layout manager itself.
One way to introduce animations in the allocation sequence is to use a
Timeline and an Alpha to compute a progress value and then use that
value to interpolate an ActorBox between the initial and final states of
the animation - with the initial state being the last allocation of the
child prior to the animation start, and the final state the allocation
of the child at the end; for every frame of the Timeline we then queue a
relayout on the layout manager's container, which will result in an
animation.
ClutterLayoutManager is the most likely place to add a generic API for
beginning and ending an animation, as well as the place to provide a
default code path to create the ancillary Timeline and Alpha instances
needed to drive the animation.
A LayoutManager sub-class will need to:
• call clutter_layout_manager_begin_animation() whenever it should
animate between two states, for instance: whenever a layout property
changes value;
• eventually override begin_animation() and end_animation() in case
further state needs to be set up, and then chain up to the default
implementation provided by LayoutManager;
• if a completely different implementation is required, the layout
manager sub-class should override begin_animation(), end_animation()
and get_animation_progress().
Inside the allocate() implementation the sub-class should also
interpolate between the last known allocation of a child and the newly
computed allocation.
ClutterActorBox should have an interpolate() method that allows to
compute the intermediate values between two states, given a progress
value, e.g.:
clutter_actor_box_interpolate (start, end, alpha, &result);
Another utility method, useful for layout managers, is a modifier
that clamps the members of the actor box to the nearest integer
value.
When getting signals from higher level toolkits, occasionally
one wants access to the underlying event; say for a Button
widget's "clicked" signal, to get the keyboard state.
Rather than having all of the highlevel widgets emit
ClutterEvent just for the more unusual use cases,
add a global function to access the event state.

This adds a new texture backend which represents a sub texture of a
larger texture. The texture is created with a reference to the full
texture and a set of coordinates describing the region. The backend
simply defers to the full texture for all operations and maps the
coordinates to the other range. You can also use coordinates outside
the range [0,1] to create a repeated version of the full texture.
A new public API function called cogl_texture_new_from_sub_texture is
available to create the sub texture.

We should always recurse into the doc/ directory; whether we should then
recurse into reference/, cookbook/ and manual/ is a matter of specific
configure-time flags.
• Make the manual a DevHelp book
• Make the generation of PDFs of the cookbook and the manual optional
• Consequently, make the hard dependency on jw optional
• Clean up the checks and build for the additional documentation
Instead of creating stand-alone HTML files, use XSLT to transform the
DocBook into a DevHelp file, so that we can read the Cookbook inside
DevHelp -- just like the API reference.
The first recipe shows how to be notified when the relative position
and size of an actor changes using the notify:: signal on the actor's
dimensional and positional properties.
The "Clutter Cookbook" is a document designed to contain solutions
to common problems applications developers might encounter when using
Clutter. It is meant as a companion to the API reference but it
requires knowledge of the Clutter API and framework.
The ClutterLayoutMeta instances should be created on demand, whenever
the layout manager needs them - if the layout manager supports layout
properties.
This removes the requirement to call add_child_meta() and
remove_child_meta() on add and remove respectively; it also simplifies
the implementation of LayoutManager sub-classes since we can add
fallback code in the base abstract class.
Eventually, this will also lead to an easier to implement ClutterScript
parser for layout properties.
With the new scheme, the ClutterLayoutMeta instance is created whenever
the layout manager tries to access it; if there isn't an instance
already attached to the container's child, one is created -- assuming
that the LayoutManager sub-class has overridden the
get_child_meta_type() virtual function and it's returning a valid GType.
We can also provide a default implementation for create_child_meta(),
by getting the GType and instantiating a ClutterLayoutMeta with all the
fields already set. If the layout manager requires more work then it can
obviously override the default implementation (and even chain up to it).
The ClutterBox actor has been updated, as well as the ClutterBoxLayout
layout manager, to take advantage of the changes of LayoutManager.
cogl_push_draw_buffer, cogl_set_draw_buffer and cogl_pop_draw_buffer are now
deprecated and new code should use the new cogl_framebuffer_* API instead.
Code that previously did:
cogl_push_draw_buffer ();
cogl_set_draw_buffer (COGL_OFFSCREEN_BUFFER, buffer);
/* draw */
cogl_pop_draw_buffer ();
should now be re-written as:
cogl_push_framebuffer (buffer);
/* draw */
cogl_pop_framebuffer ();
As can be seen from the example above the rename has been used as an
opportunity to remove the redundant target argument from
cogl_set_draw_buffer; it now only takes one call to redirect to an offscreen
buffer, and finally the term framebuffer may be a bit more familiar to
anyone coming from an OpenGL background.
This function was #if 0'd before we released Clutter 1.0 so there's no
implementation of it. At some point we thought it might assist with
developers breaking out into raw OpenGL. Breaking out to raw GL is a
difficult problem though so we decided instead we will wait for a specific
use case to arrise before trying to support it.
The Clutter API reference has an index of the symbols for each minor
version, and a list of deprecated symbols. The Cogl API reference
should have the same layout.
The order in which the MacPorts are installed is important otherwise we open
the user up to a world of pain.
This patch also tweaks the OS X docs to follow the formatting of the rest of
the docs and to discuss the option of GtkDoc.
http://bugzilla.openedhand.com/show_bug.cgi?id=1865
cogl_clip_push() which accepts a rectangle in model space shouldn't have
been defined to take x,y,width,height arguments because this isn't consistant
with other Cogl API dealing with model space rectangles. If you are using a
coordinate system with the origin at the center and the y+ extending up,
then x,y,width,height isn't as natural as (x0,y0)(x1,y1). This API has
now been replace with cogl_clip_push_rectangle()
(As a general note: the Cogl API should only use the x,y,width,height style
when the appropriate coordinate space is defined by Cogl to have a top left
origin. E.g. window coordinates, or potentially texture coordinates)
cogl_clip_push_window_rect() shouldn't have been defined to take float
arguments since we only clip with integral pixel precision. We also
shouldn't have abbreviated "rectangle". This API has been replaced with
cogl_clip_push_window_rectangle()
cogl_clip_ensure() wasn't documented at all in Clutter 1.0 and probably
no one even knew it existed. This API isn't useful, and so it's now
deprecated. If no one complains we may remove the API altogether for
Clutter 1.2.
cogl_clip_stack_save() and cogl_clip_stack_restore() were originally added
to allow us to save/restore the clip when switching to/from offscreen
rendering. Now that offscreen draw buffers are defined to own their clip
state and the state will be automatically saved and restored this API is now
redundant and so deprecated.
Just like CLUTTER_CHECK_VERSION does version checking at compile
time, we need a way to verify the version of the library that we
are linking against. This is mostly needed for language bindings
and for run-time loadable modules -- when we'll get those.
The indirection through this API isn't necessary since we no longer
arbitrate between the OpenGL matrix API and Cogl's client side API. Also it
doesn't help to maintain an OpenGL style matrix mode API for internal use
since it's awkward to keep restoring the MODELVIEW mode and easy enough to
directly work with the matrix stacks of interest.
This replaces use of the _cogl_current_matrix API with direct use of the
_cogl_matrix_stack API. All the unused cogl_current_matrix API is removed
and the matrix utility code left in cogl-current-matrix.c was moved to
cogl.c.

As part of an incremental process to have Cogl be a standalone project we
want to re-consider how we organise the Cogl source code.
Currently this is the structure I'm aiming for:
cogl/
cogl/
<put common source here>
winsys/
cogl-glx.c
cogl-wgl.c
driver/
gl/
gles/
os/ ?
utils/
cogl-fixed
cogl-matrix-stack?
cogl-journal?
cogl-primitives?
pango/
The new winsys component is a starting point for migrating window system
code (i.e. x11,glx,wgl,osx,egl etc) from Clutter to Cogl.
The utils/ and pango/ directories aren't added by this commit, but they are
noted because I plan to add them soon.
Overview of the planned structure:
* The winsys/ API is the API that binds OpenGL to a specific window system,
be that X11 or win32 etc. Example are glx, wgl and egl. Much of the logic
under clutter/{glx,osx,win32 etc} should migrate here.
* Note there is also the idea of a winsys-base that may represent a window
system for which there are multiple winsys APIs. An example of this is
x11, since glx and egl may both be used with x11. (currently only Clutter
has the idea of a winsys-base)
* The driver/ represents a specific varient of OpenGL. Currently we have "gl"
representing OpenGL 1.4-2.1 (mostly fixed function) and "gles" representing
GLES 1.1 (fixed funciton) and 2.0 (fully shader based)
* Everything under cogl/ should fundamentally be supporting access to the
GPU. Essentially Cogl's most basic requirement is to provide a nice GPU
Graphics API and drawing a line between this and the utility functionality
we add to support Clutter should help keep this lean and maintainable.
* Code under utils/ as suggested builds on cogl/ adding more convenient
APIs or mechanism to optimize special cases. Broadly speaking you can
compare cogl/ to OpenGL and utils/ to GLU.
* clutter/pango will be moved to clutter/cogl/pango
How some of the internal configure.ac/pkg-config terminology has changed:
backendextra -> CLUTTER_WINSYS_BASE # e.g. "x11"
backendextralib -> CLUTTER_WINSYS_BASE_LIB # e.g. "x11/libclutter-x11.la"
clutterbackend -> {CLUTTER,COGL}_WINSYS # e.g. "glx"
CLUTTER_FLAVOUR -> {CLUTTER,COGL}_WINSYS
clutterbackendlib -> CLUTTER_WINSYS_LIB
CLUTTER_COGL -> COGL_DRIVER # e.g. "gl"
Note: The CLUTTER_FLAVOUR and CLUTTER_COGL defines are kept for apps
As the first thing to take advantage of the new winsys component in Cogl;
cogl_get_proc_address() has been moved from cogl/{gl,gles}/cogl.c into
cogl/common/cogl.c and this common implementation first trys
_cogl_winsys_get_proc_address() but if that fails then it falls back to
gmodule.
Input Methods require to be able to set a "pre-edit string", that is
a string that it's just displayed into the Text actor without being
committed to the actor's buffer. The string might require custom Pango
attributes, and an update of the cursor position.
FlowLayout is a layout manager that arranges its children in a
reflowing line; the orientation controls the major axis for the
layout: horizontal, for reflow on the Y axis, and vertical, for
reflow on the X axis.
The BinLayout should store a pointer to the Container that it is
using it as the layout manager.
This allows us to fix the API and drop the additional Container
arguments from set_alignment() and get_alignment().
This also allows us to add a ClutterBinLayout::add() method which
adds an actor and sets the alignment policies without dealing with
variadic arguments functions and GValue (de)marshalling.
Use the LayoutManager API to set a back pointer to the Box actor
inside the LayoutManager used by the box.
This also allows us to replace the LayoutManager on a Box, since
the LayoutManager will be able to replace all the metadata if
needed.
The LayoutManager implementation might opt to take a back pointer
to the Container that is using the layout instance; this allows
direct access to the container itself from within the implementation.
The ClutterBox::add method is a simple wrapper around the Container
add_actor() method and the LayoutManager layout properties API. It
allows adding an actor to a Box and setting the layout properties in
one call.
If the LayoutManager used by the Box does not support layout properties
then the add() method short-circuits out.
Along with the varargs version of the method there's also a vector-based
variant, for language bindings to use.
Instead of overloading ClutterChildMeta with both container and layout
metadata and delegate to every LayoutManager implementation to keep a
backpointer to the layout manager instance, we can simply subclass
ChildMeta into LayoutMeta and presto! everything works out pretty well
for everyone.
The chapter on how to subclass ClutterActor inside the API reference for
Clutter is still using ClutterUnit and referencing to concepts that have
been changed since the document was written.
ClutterBehaviourPath has been changed and ClutterBehaviourBspline has
been removed; now we use ClutterPath everywhere we need to describe a
path. This warrants a chapter in the migration guide.
The get_type() function for ClutterInterval is missing from the
known GObject types, so gtk-doc doesn't know that it has to
introspect it for hierarchy, properties and signals.
Currently, to update a property inside an animation you have to
get the interval for that property and then call the set_final_value()
method.
We can provide a simpler, bind()-like method for the convenience of
the developers that just validates everything and then calls the
Interval.set_final_value().
The version number in the title made sense when we were breaking
API with every minor release. Now that we're API stable we can
drop that and make the output in Devhelp and on the website slightly
more good looking.
We should follow the convention for boxed types initializers of:
<type_name>_from_<another_type> (boxed, value)
For ClutterUnits as well; so:
clutter_units_pixels -> clutter_units_from_pixels
clutter_units_em -> clutter_units_from_em
...
We should still keep the short-hand version as a macro, though.
It might be desirable for some applications and/or platforms to get
every motion event that was delivered to Clutter from the windowing
backend. By adding a per-stage flag we can bypass the throttling
done when processing the events.

It would be useful inside a custom actor's paint function to be able to
tell if this is a primary paint call, or if we are in fact painting on
behalf of a clone.
In Mutter we have an optimization not to paint occluded windows; this is
desirable for the windows per se, to conserve bandwith to the card, but
if something like an application switcher is using clones of these windows,
they will not get painted either; currently we have no way of
differentiating between the two.
Fixes bug:
http://bugzilla.openedhand.com/show_bug.cgi?id=1685
Currently, the transformation matrix for an actor is constructed
from scenegraph-related accessors. An actor, though, can call COGL
API to add new transformations inside the paint() implementation,
for instance:
static void
my_foo_paint (ClutterActor *a)
{
...
cogl_translate (-scroll_x, -scroll_y, 0);
...
}
Unfortunately these transformations will be completely ignored by
the scenegraph machinery; for instance, getting the actor-relative
coordinates from event coordinates is going to break badly because
of this.
In order to make the scenegraph aware of the potential of additional
transformations, we need a ::apply_transform() virtual function. This
vfunc will pass a CoglMatrix which can be used to apply additional
operations:
static void
my_foo_apply_transform (ClutterActor *a, CoglMatrix *m)
{
CLUTTER_ACTOR_CLASS (my_foo_parent_class)->apply_transform (a, m);
...
cogl_matrix_translate (m, -scroll_x, -scroll_y, 0);
...
}
The ::paint() implementation will be called with the actor already
using the newly applied transformation matrix, as expected:
static void
my_foo_paint (ClutterActor *a)
{
...
}
The ::apply_transform() implementations *must* chain up, so that the
various transformations of each class are preserved. The default
implementation inside ClutterActor applies all the transformations
defined by the scenegraph-related accessors.
Actors performing transformations inside the paint() function will
continue to work as previously.
Although we wouldn't recommend developers try and interleve OpenGL drawing
with Cogl drawing - we would prefer patches that improve Cogl to avoid this
if possible - we are providing a simple mechanism that will at least give
developers a fighting chance if they find it necissary.
Note: we aren't helping developers change OpenGL state to modify the
behaviour of Cogl drawing functions - it's unlikley that can ever be
reliably supported - but if they are trying to do something like:
- setup some OpenGL state.
- draw using OpenGL (e.g. glDrawArrays() )
- reset modified OpenGL state.
- continue using Cogl to draw
They should surround their blocks of raw OpenGL with cogl_begin_gl() and
cogl_end_gl():
cogl_begin_gl ();
- setup some OpenGL state.
- draw using OpenGL (e.g. glDrawArrays() )
- reset modified OpenGL state.
cogl_end_gl ();
- continue using Cogl to draw
Again; we aren't supporting code like this:
- setup some OpenGL state.
- use Cogl to draw
- reset modified OpenGL state.
When the internals of Cogl evolves, this is very liable to break.
cogl_begin_gl() will flush all internally batched Cogl primitives, and emit
all internal Cogl state to OpenGL as if it were going to draw something
itself.
The result is that the OpenGL modelview matrix will be setup; the state
corresponding to the current source material will be setup and other world
state such as backface culling, depth and fogging enabledness will be also
be sent to OpenGL.
Note: no special material state is flushed, so if developers want Cogl to setup
a simplified material state it is the their responsibility to set a simple
source material before calling cogl_begin_gl. E.g. by calling
cogl_set_source_color4ub().
Note: It is the developers responsibility to restore any OpenGL state that they
modify to how it was after calling cogl_begin_gl() if they don't do this then
the result of further Cogl calls is undefined.
This function should only need to be called in exceptional circumstances
since Cogl can normally determine internally when a flush is necessary.
As an optimization Cogl drawing functions may batch up primitives
internally, so if you are trying to use raw GL outside of Cogl you stand a
better chance of being successful if you ask Cogl to flush any batched
geometry before making your state changes.
cogl_flush() ensures that the underlying driver is issued all the commands
necessary to draw the batched primitives. It provides no guarantees about
when the driver will complete the rendering.
This provides no guarantees about the GL state upon returning and to avoid
confusing Cogl you should aim to restore any changes you make before
resuming use of Cogl.
If you are making state changes with the intention of affecting Cogl drawing
primitives you are 100% on your own since you stand a good chance of
conflicting with Cogl internals. For example clutter-gst which currently
uses direct GL calls to bind ARBfp programs will very likely break when Cogl
starts to use ARBfb programs internally for the material API, but for now it
can use cogl_flush() to at least ensure that the ARBfp program isn't applied
to additional primitives.
This does not provide a robust generalized solution supporting safe use of
raw GL, its use is very much discouraged.
To allow for flushing of batched geometry within Cogl we can't support users
directly calling glReadPixels. glReadPixels is also awkward, not least
because it returns upside down image data.
All the unit tests have been swithed over and clutter_stage_read_pixels now
sits on top of this too.
The clutter_actor_pick() function just emits the ::pick signal
on the actor. Nobody should be using it, since the paint() method
is already context sensitive and will result in a ::pick emission
by itself. The clutter_actor_pick() is just confusing things.
The Clutter API reference should have a section on how to port
applications from older version of Clutter to the new API.
The first guide deals on how to port animations created with
ClutterEffect to clutter_actor_animate().
ActorBox should have methods for easily extracting the X and Y
coordinates of the origin, and the width and height separately.
These methods will make it easier for high-level language bindings
to manipulate ActorBox instances and avoid the Geometry type.
The Vertex and ActorBox boxed types are meant to be used across
the API, but are fairly difficult to bind. Their memory management
is also unclear, and has to go through the indirection of
g_boxed_copy() and g_boxed_free().

The clutter_redraw() function is used by embedding toolkits to
force a redraw on a stage. Since everything is performed by
toggling a flag inside the Stage itself and then letting the
master clock advance, we need a ClutterStage method to ensure
that we start the master clock and redraw.
The clutter_stage_fullscreen() and clutter_stage_unfullscreen() are
a GDK-ism. The underlying implementation is already using an accessor
with a boolean parameter.
This should take the amount of collisions between properties, methods
and signals to zero.
ClutterEvent is not really gobject-introspection friendly because
of the whole discriminated union thing. In particular, if you get
a ClutterEvent in a signal handler, you probably can't access the
event-type-specific fields, and you probably can't call methods
like clutter_key_event_symbol() either, because you can't cast the
ClutterEvent to a ClutterKeyEvent.
The cleanest solution is to turn every accessor into ClutterEvent
methods, accepting a ClutterEvent* and internally checking the event
type.

The texture filters are now a property of the material layer rather
than the texture object. Whenever a texture is painted with a material
it sets the filters on all of the GL textures in the Cogl texture. The
filter is cached so that it won't be changed unnecessarily.
The automatic mipmap generation has changed so that the mipmaps are
only generated when the texture is painted instead of every time the
data changes. Changing the texture sets a flag to mark that the
mipmaps are dirty. This works better if the FBO extension is available
because we can use glGenerateMipmap. If the extension is not available
it will temporarily enable automatic mipmap generation and reupload
the first pixel of each slice. This requires tracking the data for the
first pixel.
The COGL_TEXTURE_AUTO_MIPMAP flag has been replaced with
COGL_TEXTURE_NO_AUTO_MIPMAP so that it will default to
auto-mipmapping. The mipmap generation is now effectively free if you
are not using a mipmap filter mode so you would only want to disable
it if you had some special reason to generate your own mipmaps.
ClutterTexture no longer has to store its own copy of the filter
mode. Instead it stores it in the material and the property is
directly set and read from that. This fixes problems with the filters
getting out of sync when a cogl handle is set on the texture
directly. It also avoids the mess of having to rerealize the texture
if the filter quality changes to HIGH because Cogl will take of
generating the mipmaps if needed.
Units as they have been implemented since Clutter 0.4 have always been
misdefined as "logical distance unit", while they were just pixels with
fractionary bits.
Units should be reworked to be opaque structures to hold a value and
its unit type, that can be then converted into pixels when Clutter needs
to paint or compute size requisitions and perform allocations.
The previous API should be completely removed to avoid collisions, and
a new type:
ClutterUnits
should be added; the ability to install GObject properties using
ClutterUnits should be maintained.
Timelines no longer work in terms of a frame rate and a number of
frames but instead just have a duration in milliseconds. This better
matches the working of the master clock where if any timelines are
running it will redraw as fast as possible rather than limiting to the
lowest rated timeline.
Most applications will just create animations and expect them to
finish in a certain amount of time without caring about how many
frames are drawn. If a frame is going to be drawn it might as well
update all of the animations to some fraction of the total animation
rather than rounding to the nearest whole frame.
The 'frame_num' parameter of the new-frame signal is now 'msecs' which
is a number of milliseconds progressed along the
timeline. Applications should use clutter_timeline_get_progress
instead of the frame number.
Markers can now only be attached at a time value. The position is
stored in milliseconds rather than at a frame number.
test-timeline-smoothness and test-timeline-dup-frames have been
removed because they no longer make sense.
Clutter copies the gtk-doc from the usual gtk+ template, and
has a version.xml.in containing only:
@VERSION@
Without a newline at the end. Unfortunately, it appears that
autoconf has started adding a newline to the generated version.xml
which then is used as the payload for the "version" XML entity.
Instead of using a secondary file we can make configure generate
the whole clutter-docs.xml and cogl-docs.xml files from a template;
this way we also get the ability to substitute more autoconf variables
into the documentation -- if needs be.
This function can be used as an efficient way of drawing groups of
quads without using GL_QUADS. It generates a VBO containing the
indices needed to render using pairs of GL_TRIANGLES. The VBO is
globally cached so that it only needs to be uploaded whenever more
indices are requested than ever before.
The allocate_available_size() method is a convenience method in
the same spirit as allocate_preferred_size(). While the latter
will allocate the preferred size of an actor regardless of the
available size provided by the actor's parent -- and thus it's
suitable for simple fixed layout managers like ClutterGroup -- the
former will take into account the available size provided by the
parent and never allocate more than that; it is, thus, suitable
for simple fluid layout managers.
cogl_enable_depth_test and cogl_enable_backface_culling have been renamed
and now have corresponding getters, the new functions are:
cogl_set_depth_test_enabled
cogl_get_depth_test_enabled
cogl_set_backface_culling_enabled
cogl_get_backface_culling_enabled
This adds cogl_matrix api for multiplying matrices either by a perspective
or ortho projective transform. The internal matrix stack and current-matrix
APIs also have corresponding support added.
New public API:
cogl_matrix_perspective
cogl_matrix_ortho
cogl_ortho
cogl_set_modelview_matrix
cogl_set_projection_matrix
cogl_create_context is dealt with internally when _cogl_get_default context
is called, and cogl_destroy_context is currently never called.
It might be nicer later to get an object back when creating a context so
Cogl can support multiple contexts, so these functions are being removed
from the API until we get a chance to address context management properly.
For now cogl_destroy_context is still exported as _cogl_destroy_context so
Clutter could at least install a library deinit handler to call it.
Originally cogl_vertex_buffer_add_indices let the user pass in their own unique
ID for the indices; now the Id is generated internally and returned to the
caller.
It's now possible to add arrays of indices to a Cogl vertex buffer and
they will be put into an OpenGL vertex buffer object. Since it's quite
common for index arrays to be static it saves the OpenGL driver from
having to validate them repeatedly.
This changes the cogl_vertex_buffer_draw_elements API: It's no longer
possible to provide a pointer to an index array at draw time. So
cogl_vertex_buffer_draw_elements now takes an indices identifier that
should correspond to an idendifier returned when calling
cogl_vertex_buffer_add_indices ()
There were a number of functions intended to support creating of new
primitives using materials, but at this point they aren't used outside of
Cogl so until someone has a usecase and we can get feedback on this
API, it's being removed before we release Clutter 1.0.
This removes the following API:
cogl_material_set_blend_factors
cogl_material_set_layer_combine_function
cogl_material_set_layer_combine_arg_src
cogl_material_set_layer_combine_arg_op
These were rather awkward to use, so since it's expected very few people are
using them at this point and it should be straight forward to switch over
to blend strings, the API is being removed before we release Clutter 1.0.
Setting up layer combine functions and blend modes is very awkward to do
programatically. This adds a parser for string based descriptions which are
more consise and readable.
E.g. a material layer combine function could now be given as:
"RGBA = ADD (TEXTURE[A], PREVIOUS[RGB])"
or
"RGB = REPLACE (PREVIOUS)"
"A = MODULATE (PREVIOUS, TEXTURE)"
The simple syntax and grammar are only designed to expose standard fixed
function hardware, more advanced combining must be done with shaders.
This includes standalone documentation of blend strings covering the aspects
that are common to blending and texture combining, and adds documentation
with examples specific to the new cogl_material_set_blend() and
cogl_material_layer_set_combine() functions.
Note: The hope is to remove the now redundant bits of the material API
before 1.0
ClutterTexture has many properties that can only be accessed using
the GObject API. This is fairly inefficient and makes binding the
class overly complicated.
The Texture class should have accessor methods for all its properties,
properly documented.
Add a method for deleting the current selection inside a Text actor.
This is useful for subclasses.

COGLenum, COGLint and COGLuint which were simply typedefs for GL{enum,int,uint}
have been removed from the API and replaced with specialised enum typedefs, int
and unsigned int. These were causing problems for generating bindings and also
considered poor style.
The cogl texture filter defines CGL_NEAREST and CGL_LINEAR etc are now replaced
by a namespaced typedef 'CoglTextureFilter' so they should be replaced with
COGL_TEXTURE_FILTER_NEAREST and COGL_TEXTURE_FILTER_LINEAR etc.
The shader type defines CGL_VERTEX_SHADER and CGL_FRAGMENT_SHADER are handled by
a CoglShaderType typedef and should be replaced with COGL_SHADER_TYPE_VERTEX and
COGL_SHADER_TYPE_FRAGMENT.
cogl_shader_get_parameteriv has been replaced by cogl_shader_get_type and
cogl_shader_is_compiled. More getters can be added later if desired.

There were several functions I believe no one is currently using that were
only implemented in the GL backend (cogl_offscreen_blit_region and
cogl_offscreen_blit) that have simply been removed so we have a chance to
think about design later with a real use case.
There was one nonsense function (cogl_offscreen_new_multisample) that
sounded exciting but in all cases it just returned COGL_INVALID_HANDLE
(though at least for GL it checked for multisampling support first!?)
it has also been removed.
The MASK draw buffer type has been removed. If we want to expose color
masking later then I think it at least would be nicer to have the mask be a
property that can be set on any draw buffer.
The cogl_draw_buffer and cogl_{push,pop}_draw_buffer function prototypes
have been moved up into cogl.h since they are for managing global Cogl state
and not for modifying or creating the actual offscreen buffers.
This also documents the API so for example desiphering the semantics of
cogl_offscreen_new_to_texture() should be a bit easier now.
Bug 1138 - No trackable "mapped" state
* Add a VISIBLE flag tracking application programmer's
expected showing-state for the actor, allowing us to
always ensure we keep what the app wants while tracking
internal implementation state separately.
* Make MAPPED reflect whether the actor will be painted;
add notification on a ClutterActor::mapped property.
Keep MAPPED state updated as the actor is shown,
ancestors are shown, actor is reparented, etc.
* Require a stage and realized parents to realize; this means
at realization time the correct window system and GL resources
are known. But unparented actors can no longer be realized.
* Allow children to be unrealized even if parent is realized.
Otherwise in effect either all actors or no actors are realized,
i.e. it becomes a stage-global flag.
* Allow clutter_actor_realize() to "fail" if not inside a toplevel
* Rework clutter_actor_unrealize() so internally we have
a flavor that does not mess with visibility flag
* Add _clutter_actor_rerealize() to encapsulate a somewhat
tricky operation we were doing in a couple of places
* Do not realize/unrealize children in ClutterGroup,
ClutterActor already does it
* Do not realize impl by hand in clutter_stage_show(),
since showing impl already does that
* Do not unrealize in various dispose() methods, since
ClutterActor dispose implementation already does it
and chaining up is mandatory
* ClutterTexture uses COGL while unrealizable (before it's
added to a stage). Previously this breakage was affecting
ClutterActor because we had to allow realize outside
a stage. Move the breakage to ClutterTexture, by making
ClutterTexture just use COGL while not realized.
* Unrealize before we set parent to NULL in clutter_actor_unparent().
This means unrealize() implementations can get to the stage.
Because actors need the stage in order to detach from stage.
* Update clutter-actor-invariants.txt to reflect latest changes
* Remove explicit hide/unrealize from ClutterActor::dispose since
unparent already forces those
Instead just assert that unparent() occurred and did the right thing.
* Check whether parent implements unrealize before chaining up
Needed because ClutterGroup no longer has to implement unrealize.
* Perform unrealize in the default handler for the signal.
This allows non-containers that have children to work properly,
and allows containers to override how it's done.
* Add map/unmap virtual methods and set MAPPED flag on self and
children in there. This allows subclasses to hook map/unmap.
These are not signals, because notify::mapped is better for
anything it's legitimate for a non-subclass to do.

Bug 1513 - Allow passing in ClutterPickMode to
clutter_stage_get_actor_at_pos()
At the moment, clutter_stage_get_actor_at_pos() uses CLUTTER_PICK_ALL
internally to find an actor. It would be useful to allow passing in
ClutterPickMode to clutter_stage_get_actor_at_pos(), so that the caller
can specify CLUTTER_PICK_REACTIVE as a criteria.
Adds a new property so that the selection color can be different from
the cursor color. If no selection color is specified it will use the
cursor color as before. If no cursor color is specified either it will
use the text color.
ClutterGroup still ships with API deprecated since 0.4. We did
promise to keep it around for a minor release cycle -- not for 3.
Since we plan on shipping 1.0 without the extra baggage of the
deprecated entry points, here's the chance to remove the accumulated
cruft.
All the removed methods and signals have a ClutterContainer
counterpart.
Since we're planning to release 1.0 without any of the deprecated
API baggage, we can simply remove the set_uniform_1f() method from
ClutterShader public API and add it to the deprecated header.
This function was renamed a while ago in the .c file from
cogl_vertex_buffer_draw_range_elements but the corresponding .h and
doc/reference/cogl changes weren't made.
The Animation API should follow this pattern:
- functions with an Interval as part of the arguments should have
"interval" inside their name, e.g.:
clutter_animation_bind_interval
clutter_animation_update_interval
- functions dealing with property names should have "property"
inside their name, e.g.:
clutter_animation_has_property
clutter_animation_unbind_property
- unless -
- functions dealing with a property and its value should not
have any modifier, e.g.:
clutter_animation_bind
The change from update_property() to update_interval() frees up
clutter_animation_update(), to be added at a later date.
Bug 1438 - Implicit Animation API could use animatev variants
The clutter_actor_animate* family of functions use va_lists to
handle the property/value pairs for the final state of the
animation.
Language bindings have problems with variadic arguments functions,
and usually prefer vector-based API which allow a greater level
of control and conversion from native data types.
For each variadic arguments function in the clutter_actor_animate*
family there should be a vector-based version that takes:
- the number of property/value pairs
- a constant array of constant strings
- an array of GValues
Most of the internal implementation can be refactored from the
current one, thus both the var_args and the vector entry points
share a common implementation of the code; then, both versions
of the API are just loops over a list of arguments.
Based on a patch by: Robert Carr <carrr@rpi.edu>
The ClutterColor API has some inconsistencies:
- the string deserialization function does not match the rest of
the conversion function naming policy; the naming should be:
clutter_color_parse() -> clutter_color_from_string()
and the first parameter should be the ClutterColor that will
be set from the string, not the string itself (a GDK-ism).
- the fixed point API should not be exposed, especially in the
form of ClutterFixed values
- the non-fixed point HLS conversion functions do not make any
sense. The values returned should be:
hue := range [ 0, 360 ]
luminance := range [ 0, 1 ]
saturation := range [ 0, 1 ]
like the current fixed point API does. Returning a value in
the [ 0, 255 ] range is completely useless
- the clutter_color_equal() should be converted for its use inside
a GHashTable; a clutter_color_hash() should be added as well
- the second parameter of the clutter_color_shade() function should
be the shading factor, not the result (another GDK-ism). this way
the function call can be translated from this:
color.shade(out result, factor)
to the more natural:
color.shade(factor, out result)
This somewhat large commit fixes all these issues and updates the
internal users of the API.
In the future if we want to annotate matrices with internal flags, and add
caching of the inverse matrix then we need to ensure that all matrix
modifications are done by cogl_matrix API so we'd know when to dirty the
cache or update the flags.
This just adds documentation to that effect, and assuming the most likley
case where someone would try and directly write to matrix members would
probably be to load a constant matrix other than the identity matrix; I
renamed cogl_matrix_init_from_gl_matrix to cogl_matrix_init_from_array to
make it seem more general purpose.
Clutter uses checks on various environment variables and installs
various command line switches. The API reference should list them
and document them both.
The COGL_DEFINE_HANDLE macro generates a cogl_is_<type> function
as well, to check whether a CoglHandle opaque pointer is of type
<type>.
The handle for CoglMaterial does not export cogl_is_material() in
its installed header.
cogl_paint_init was a bit too miscellaneous; it mainly cleared the color, depth
and stencil buffers but arbitrarily it also disabled fogging and lighting.
It no longer disables lighting, since we know Cogl never enables lighting and
disabling of fog is now handled with a seperate function.
Since I noticed cogl_set_fog was taking a density argument documented as
"Ignored" I've also added a mode argument to cogl_set_fog which exposes the
exponential fog modes which can make use of the density.
This hides a number of internal structs and enums from the docs, and moves
some functions to more appropriate sections as well as misc description
updates (mostly for the vertex buffer api)
The :alignment property is prone to generate confusion: developers
will set it thinking that the contents of a ClutterText will
automagically align themselves.
Instead of using the generic term :alignment, and following the
GTK+ convention, we should use a more specific term, conveying the
actual effect of the property: alignment of the lines with respect
to each other, and not to the overall allocated area.
See bug 1428:

Final bit of integration between ClutterActor and Pango: a simple
method for creating a PangoLayout, pre-filled with text and ready
to be rendered using cogl_pango_render_layout().
This should make writing new Actors rendering custom text in their
paint() implementation easy and reliable.
The Alpha API and usage has been changed by the recent overhaul
of the ClutterAlpha class; hence, we need to update the relative
documentation in the animation tutorial.
Bug 1349 - Using the anchor point to set the scale center is messy
The branch adds an extra center point for scaling which can be used
for example to set a scale about the center without affecting the
position of the actor.
The scale center can be specified as a unit offset from the origin or
as a gravity. If specified as a gravity it will be stored as a
fraction of the actor's size so that the position will track when the
actor changes size.
The anchor point and rotation centers have been modified so they can
be set with a gravity in the same way. However, only the Z rotation
exposes a property to set using a gravity because the other two
require a Z coordinate which doesn't make sense to interpret as a
fraction of the actor's width or height.

ClutterClone supercedes ClutterCloneTexture, since it can clone
every kind of actor -- including composite ones.
This is another "brain surgery with a shotgun" kind of commit: it
removes CloneTexture and updates every test case using CloneTexture
to ClutterClone. The API fallout is minimal, luckily for us.
The hope is that this function makes it easier to extend the font
settings with more flags without having to add a function for every
setting.
A new flag for enabling hinting has been added. If set, this changes
the font options on the global PangoContext and any newly created
PangoContexts. The options are only set if the flag is changed from
the default so it won't override any detailed setting chosen by the
backend.
The documentation has been updated to reflect the fact that the anchor
point will move when the actor changes size if it was specified using
a gravity value. The new functions for setting the scale center and z
rotation gravity are also documented.
The clutter_stage_get_resolution() and fixed-point API are just
shorthands for:
clutter_backend_get_resolution (default_backend);
And as such do not fit at all in the ClutterStage class. The only
reason for their existence was the ClutterUnit conversion macros,
which have now been fixed to use the default backend through a
function call instead.
Thus, we can safely remove the stage entry points.

An em is a unit of measurement in typography, equal to the point
size of the current font.
It should be possible to convert a value expressed in em to
ClutterUnits by using the current font and the current DPI as
stored by the default backend.
The stage-with/height-percentage converters had been broken by
the multiple-stages support of Clutter 0.8. They are also made
useless by the fact that Units are now floating point values.
The millimeters and typographic points converters also depended
on the default stage, but they can be reworked to use the default
DPI coming from the default Backend instead.
This better reflects the fact that the api manages sets of vertex attributes,
and the attributes really have no implied form. It is only when you use the
attributes to draw that they become mesh like; when you specify how they should
be interpreted, e.g. as triangle lists or fans etc. This rename frees up the
term "mesh", which can later be applied to a concept slightly more fitting.
E.g. at some point it would be nice to have a higher level abstraction that
sits on top of cogl vertex buffers that adds the concept of faces. (Somthing
like Blender's mesh objects.) There have also been some discussions over
particle engines, and these can be defined in terms of emitter faces; so some
other kind of mesh abstraction might be usefull here.
Okey; to summarise the changes...
We have converted Clutter and Cogl over to using floating point internally
instead of 16.16 fixed, but we have maintained the cogl-fixed API as a
utility to applications in case they want to implement their own optimizations.
The Clutter API has not changed (though ClutterFixed and ClutterUnit are now
internally floats) but all Cogl entry points have been changed to accept floats
now instead of CoglFixed.
To summarise the rationale...
There have been a number of issues with using fixed point though out Clutter
and Cogl including: lack of precision, lack of range, excessive format
conversion (GPUs tend to work nativly with IEEE floats) and maintainability.
One of the main arguments for fixed point - performance - hasn't shown
itself to be serious in practice so far since we seem to be more limited
by GPU performance and making improvements regarding how we submit data to
OpenGL[ES]/the GPU has had a more significant impact.
Ref: The recent multiple rectangle queuing changes + the
cogl-texture-agressive-batching branch which show significant performance
gains, and that recent tests on the ipodtouch (ARM + MBX) also showed no
loss of performance running with floats.
So finally; please forgive the inevitable fallout, this is a far reaching
change. There are still a few known issues with the fixed to float
conversion but enough works for all our conformance tests to pass, and the
remaining issues hopefully wont be too tricky to solve. For reference two
tags will be available either side of this change: "cogl-fixed-end" and
"cogl-float-start"
The ClutterAlpha API reference page should also list the
easing modes Clutter provides by default, by showing the
curves used by each entry in the AnimationMode enumeration.
We can also remove the incomplete graph showing the old
alpha functions.
To deal with all the corner cases that couldn't be scripted a number of patches
were written for the remaining 10% of the effort.
Note: again no API changes were made in Clutter, only in Cogl.
In order to unify alpha functions and animation modes in ClutterAlpha
we should be able to register alpha functions and get a logical id
for them; the logical id will then be available to be used by
clutter_alpha_set_mode().
The registration requires API changes in ClutterAlpha constructors
and methods. It also provides the chance to shift ClutterAlpha
towards the use of animations modes only, and to alpha functions
as a convenience API for language bindings alone.
The Effects API and all related symbols have been superceded by
the newly added Animation API and clutter_actor_animate().
This commit removes the Effects implementation, the documentation
and the interactive test/example code.

Bug 1289 - Draw multiple glyphs at once
The multiple-texture-rectangle branch adds a new Cogl texture function
called cogl_texture_multiple_rectangles which is used to draw multiple
rectangles out of a texture using a single GL call. This is
significantly faster than drawing the rectangles with individual calls
on some platforms. The Pango renderer now uses this to speed up
rendering.

[text] Coalesce text visibility and password character
Allow localizations to change the text direction
Clean up the update_pango_context() function
Pass the PangoContext, not the MainContext
Revert the logic of the PangoContext check
Remove the binding pool entry from the list
Remove BindingPool::list_actions()
Add ClutterActor::create_pango_context()
Rename the PangoContext creation functions
...
The clutter_binding_pool_list_actions() was not implemented. The
utility of a call listing all the action names is also debatable:
all the functions related to the key bindings take the key symbol
and modifiers -- except the block_action() and unblock_action()
pair.
Add all the unused API to the sections file; there are still
some undocumented bits, but clutter-unused.txt is empty for
the time being.
Also, add ClutterText to the main XML document and remove
ClutterLabel and ClutterEntry.

* clutter/cogl/common/cogl-primitives.h:
* clutter/cogl/gl/cogl-primitives.c:
* clutter/cogl/gles/cogl-primitives.c: Changed the semantics of
cogl_path_move_to. Previously this always started a new path but
now it instead starts a new disjoint sub path. The path isn't
cleared until you call either cogl_path_stroke, cogl_path_fill or
cogl_path_new. There are also cogl_path_stroke_preserve and
cogl_path_fill_preserve functions.
* clutter/cogl/gl/cogl-context.c:
* clutter/cogl/gl/cogl-context.h:
* clutter/cogl/gles/cogl-context.c:
* clutter/cogl/gles/cogl-context.h: Convert the path nodes array
to a GArray.
* clutter/cogl/gl/cogl-texture.c:
* clutter/cogl/gles/cogl-texture.c: Call cogl_clip_ensure
* clutter/cogl/common/cogl-clip-stack.c:
* clutter/cogl/common/cogl-clip-stack.h: Simplified the clip
stack code quite a bit to make it more maintainable. Previously
whenever you added a new clip it would go through a separate route
to immediately intersect with the current clip and when you
removed it again it would immediately rebuild the entire clip. Now
when you add or remove a clip it doesn't do anything immediately
but just sets a dirty flag instead.
* clutter/cogl/gl/cogl.c:
* clutter/cogl/gles/cogl.c: Taken away the code to intersect
stencil clips when there is exactly one stencil bit. It won't work
with path clips and I don't know of any platform that doesn't have
eight or zero stencil bits. It needs at least three bits to
intersect a path with an existing clip. cogl_features_init now
just decides you don't have a stencil buffer at all if you have
less than three bits.
* clutter/cogl/cogl.h.in: New functions and documentation.
* tests/interactive/test-clip.c: Replaced with a different test
that lets you add and remove clips. The three different mouse
buttons add clips in different shapes. This makes it easier to
test multiple levels of clipping.
* tests/interactive/test-cogl-primitives.c: Use
cogl_path_stroke_preserve when using the same path again.
* doc/reference/cogl/cogl-sections.txt: Document the new
functions.

the alpha functions. They will be replaced by entries in the
ClutterAnimationMode.
* clutter/clutter-interval.[ch]: Add ClutterInterval, an
object for defining, validating and computing an interval
between two values.
* clutter/clutter-animation.[ch]: Add ClutterAnimation, an
object responsible for animation the properties of a single

management is automatic. A simple wrapper method for
ClutterActor is provided:

avoid clashes with the ClutterAnimation section.
* doc/reference/clutter/clutter-docs.sgml: Renamed to
doc/reference/clutter/clutter-docs.xml, as it was an XML
file and not a SGML file.

to the deprecations and new alpha API.
* clutter/cogl/cogl-color.h:
* clutter/cogl/cogl-path.h:
* clutter/cogl/cogl-types.h:
* clutter/cogl/common/cogl-color.c: Deprecated cogl_color()
in favour of cogl_set_source_color() and friends; store the
CoglColor components as unsigned bytes instead of fixed point
normalized values; add functions for allocating, copying and
freeing CoglColor, for use of language bindings.
* clutter/cogl/cogl.h.in:

The Mesh API provides a means for submitting an extensible number of
per vertex attributes to OpenGL in a way that doesn't require format
conversions and so that the data can be mapped into the GPU (in vertex
buffer objects) for - hopefully - fast re-use.
There are a number of things we can potentially use this API for, but
right now this just provides a foundation to build on. Please read
the extensive list of TODO items in cogl-mesh.c for examples.
Please refer to the cogl-mesh section in the reference manual for
documentation of the API.

for ClutterColor. With ClutterParamSpecColor it is possible to define
color properties; with the GValue integration it's possible to
automatically transform strings into colors and vice versa.
(clutter_color_free): Allow NULL parameter to match other boxed
types destructors.
(clutter_color_new): Add a constructor for the ClutterColor boxed
type, mostly for bindings.
Bug 1099 - No ClutterScript API to get a list of IDs in a given file
* clutter/clutter-script.[ch]: Add clutter_script_list_objects(),
a function for retrieving all the objects built by a ClutterScript
instance. (Based on a patch by Noah Gibbs)
* doc/reference/clutter/subclassing-ClutterActor.xml: Update the
custom actor example since the Cogl API was changed to namespace
all of the path related functions in cogl_path_*. Thanks to Nati
Berkover.

Bug 989 - Add a search path for clutter script assets
* clutter/clutter-script.h:
* clutter/clutter-script.c:
(clutter_script_finalize),
(clutter_script_add_search_paths),
(clutter_script_lookup_filename): Add the ability to define multiple
search paths inside ClutterScript and to look up a specific filename
inside those search paths. This is useful to define a set of
directories where the assets for a UI definition are and still
reference those assets by their name instead of the full path. (989,
based on a patch by Matthew Allum)
* clutter/clutter-texture.c:
(clutter_texture_set_custom_property): Use the newly added
clutter_script_lookup_filename() function.

before 0.8.0, and we obviously need to enforce the invariants.
* doc/reference/cogl/Makefile.am: Ignore cogl/gl and cogl/gles
when building the documentation.
* clutter/cogl/cogl.h.in: Add sections in the header file.
Bug #927 - Created ports for clutter, clutter-cairo in macports
* clutter/clutter-docs.sgml: Update the OSX build instructions
and mention that the preferred way to build Clutter for developing
applications is via MacPorts. (#927, Idan Gazit)
Bug 882 - Allow child properties for containers implementing the
ClutterContainer interface (Øyvind Kolås)
* clutter/clutter-child-meta.[ch]: Base class for the metadata
of a ClutterActor inside a ClutterContainer; the ChildMeta
object implements a wrapper for storing data that is attached
to a ClutterActor only when it's part of a ClutterContainer.
The ChildMeta object is used to store the child properties
accessible through the ClutterContainer API.
* clutter/clutter-container.[ch]: Creates the ChildMeta for
each actor, in case the Container specifies the ChildMeta
type to use.
* clutter/Makefile.am: Add clutter-child-meta.[ch] to the build.
* clutter/clutter-marshal.list: Add the marshaller for the
ClutterContainer::child-notify signal.

COGL_HANDLE_DEFINE which helps build functions to create
reference-counted handles. This reduces the amount of duplicated
code.
* clutter/cogl/gl/cogl-texture.c:
* clutter/cogl/gles/cogl-texture.c:
* clutter/cogl/gl/cogl-fbo.c: Converted to use COGL_HANDLE_DEFINE

CoglHandles instead of COGLhandles. cogl_program_destroy and
cogl_shader_destroy is now replaced with cogl_program_unref and
cogl_shader_unref. cogl_program_ref and cogl_shader_ref are also
added.
* clutter/clutter-shader.c: Converted to use CoglHandles for the
programs and shaders instead of COGLhandles.
* cogl/cogl-sections.txt: Added cogl_shader_ref,
cogl_shader_unref, cogl_is_shader, cogl_program_ref,
cogl_program_unref, cogl_is_program and cogl_is_offscreen.
* clutter/clutter-docs.sgml: Add index for the 0.8 symbols.
* clutter/Makefile.am:
* cogl/Makefile.am: Revert back, as EXTRA_DIST has been defined
by gtk-doc.make and automake-1.9 complains loudly about a
redefinition of EXTRA_DIST.

* clutter/clutter-fixed.h: Add boundaries for fixed point
and units values.
* doc/reference/clutter-sections.txt: Update the documentation.
* clutter/clutter-fixed.[ch]: Add a ClutterFixed fundamental
type, and wrappers for storing it into GValues; also add a
GParamSpec subclass for defining parameters holding
ClutterFixed values. This allows creating GObject properties
using fixed point values.
* doc/reference/clutter-sections.txt: Document the newly
added API.
* clutter/Makefile.am: Add clutter-units.c
* clutter/clutter-units.[ch]: Add a ClutterUnit fundamental
type, and wrappers for storing it into GValues; also add a
GParamSpec subclass for defining parameters holding ClutterUnit
values. This allows creating GObject properties using units.
* doc/reference/clutter-sections.txt: Document the newly
added API.
* clutter/win32/clutter-win32.h:
* clutter/win32/clutter-stage-win32.h:
* clutter/win32/clutter-stage-win32.c:
* clutter/win32/clutter-event-win32.c:
* clutter/win32/clutter-backend-win32.h:
* clutter/win32/clutter-backend-win32.c:
Upgraded for multi-stage support.
* clutter/win32/clutter-stage-win32.c
(clutter_stage_win32_request_coords): Fixed so that it doesn't set
the position or size if it hasn't changed. This was causing
problems when the window was resized using the top left corner. In
that case the window receives resize and move messages separately
which caused the window to flash at a different size or position
while one message was handled before the other.
(clutter_stage_win32_realize): Added PFD_GENERIC_ACCELERATED to
the list of pixel format flags to force it to use hardware
acceleration.
2008-03-30 Neil Roberts <neil@o-hand.com>
* clutter-sections.txt: Added clutter_win32_get_stage_from_window
* clutter/win32/clutter-win32.h: Added gtk-doc documentation for
the Win32 backend section.
* clutter/win32/clutter-stage-win32.c
(clutter_win32_get_stage_window): Fixed punctuation in the
documentation.
* README: Added notes about the Win32 backend.
2008-03-26 Neil Roberts <neil@o-hand.com>
* clutter-sections.txt: Added a section for the Win32 specific
API.
* clutter-docs.sgml: Added comments about the Win32 backend.
* Makefile.am: Added bits to ignore the headers for the Win32
backend.
* clutter/clutter-score.[ch]: Remove all the API changes, and
just add a clutter_score_append_at_marker(); the implementation
remains the same, but the marker must be explicitly created by
the developer. The ids are no longer used to create implicit
markers, so they can return to be unsigned integers.
* clutter/clutter-timeline.[ch]:
(clutter_timeline_has_marker): Add a function to query a timeline
for a marker being set.
* tests/test-score.c (main): Update with the API changes.
* clutter.symbols: Update exported symbols.
* clutter/clutter-actor.[ch]:
* clutter/clutter-types.h:
* doc/reference/clutter-docs.sgml: Fix a lot of documentation.
2008-02-15 Matthew Allum <mallum@openedhand.com>
* clutter-animation.sgml: Fix some of the grammar; add a timeout-based
animation example.
* creating-your-own-behaviours.sgml: Fix some of the linking.
* subclassing-ClutterActor.sgml: Remove the FIXMEs; add the initial
structure of a section about containers.
* clutter-sections.txt: Add last-minute API additions.
* subclassing-ClutterActor.sgml: Fix some of the notes; the
Container implementation will need its own section.
* Makefile.am:
* alpha-func.png:
* event-flow.png: More figures. alpha-func.png is a graph
showing the flow of some alpha functions; event-flow.png maps
the path of an event coming from the underlying windowing
system into Clutter and through the entire library.
* Makefile.am: Use variables, instead of substitutions.
* clutter/clutter-private.h:
* clutter/clutter-main.h: Make clutter_do_event() public again,
as we need it in clutter-gtk.
* configure.ac:
* clutter/x11/Makefile.am:
* clutter/x11/clutter-x11.pc.in: Add a clutter-x11 pkg-config
file for clutter-gtk, as it depends on the X11 backend API, as
implemented by the GLX and EGLX backends.
* clutter/x11/clutter-event-x11.c (event_translate): Do not
propagate DestroyNotify events if the stage doesn't own the
window.
* tests/test-scale.c (main): Set values different from the default.
* clutter/clutter-behaviour-depth.h:
* clutter/clutter-behaviour-depth.c:
(clutter_behaviour_depth_set_bounds),
(clutter_behaviour_depth_get_bounds): Add the depth-start and
depth-end accessors.
* tests/test-depth.c (timeline_completed): Use set_bounds()
instead of g_object_set().
* clutter.symbols: Add clutter_behaviour_depth_set_bounds()
and clutter_behaviour_opacity_get_bounds() to the list of
public symbols.
* clutter.symbols: Add ClutterBehaviourOpacity accessors.
* clutter/clutter-behaviour-opacity.h:
* clutter/clutter-behaviour-opacity.c:
(clutter_behaviour_opacity_set_bounds),
(clutter_behaviour_opacity_get_bounds): Add accessors for the
opacity-start and opacity-end properties.
* clutter/clutter-behaviour-scale.h: Fix the argument name to
avoid complaints by gtk-doc.
* clutter.symbols: Add new ClutterBehaviourScale setters.
* clutter/clutter-behaviour-scale.[ch]: Split the scaling factors
on both axis. Add setters for all the behaviour properties.
* clutter/clutter-effect.h:
* clutter/clutter-effect.c (clutter_effect_scale): Split the
final scale factor to match the ClutterBehaviourScale changes. (#709)
* tests/test-actors.c:
* tests/test-effects.c:
* tests/test-rotate.c:
* tests/test-scale.c: Update after API change.
* clutter.symbols: Add clutter_model_insertv()
* clutter/clutter-model.[ch] (clutter_model_insertv): Add a vector
based insertion API, for language bindings
* clutter/clutter-model-default.[ch]: Rename ClutterModelDefault
into ClutterListModel, to make it clear that the default
ClutterModel implementation is list-based
* tests/test-model.c: Update call
* clutter/clutter-model-default.c:
(clutter_model_default_new),
(clutter_model_default_newv): Move the constructors in the
right file

the ClutterModel implementations
* clutter/clutter-model.c:
(clutter_model_check_type),
(clutter_model_set_n_columns),
(clutter_model_set_column_type): Mark as private to Clutter,
not static to ClutterModel
* clutter/Makefile.am: Add clutter-model-private.h
* clutter/clutter-model-default.[ch]: Remove the ClutterModelDefault
iterator symbols from the public API; the iterator implementation
is a detail of the default ClutterModel class
* clutter.symbols: Update
* clutter/clutter-model.h:
* clutter/clutter-model.c:
(clutter_model_appendv),
(clutter_model_prependv): Add vector based API for bindings.
(clutter_model_get_column_name),
(clutter_model_get_column_type),
(clutter_model_set_sorting_column): Fix the check in the condition
on the column index.
* tests/test-scale.c (on_timeline_completed), (main): Fix spelling
* clutter.symbols: Update public symbols
* clutter.symbols: Add clutter_actor_move_byu()
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
(clutter_actor_move_by),
(clutter_actor_move_byu): Add a units-based variant of the
clutter_actor_move_by() function
* clutter.symbols: Add clutter_actor_set_clipu() and
clutter_actor_get_clipu()
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
(clutter_actor_set_clipu), (clutter_actor_get_clipu): Add the
new units-based versions of the clip accessors
(clutter_actor_set_clip), (clutter_actor_get_clip): Reimplement
the pixels-based clip accessors as proxies for the units-based
ones
* clutter/clutter-group.c:
* clutter/clutter-group.h: Add the clutter_group_add() convenience
function; it's now "undeprecated" and implemented as a macro
* clutter/clutter-stage.h: Add clutter_stage_add() as a convenience
macro
* clutter/cogl/cogl.h: Include just the needed headers instead
of the whole clutter.h; this avoids rebuild cogl when not needed
* clutter/clutter-model-default.c:
(clutter_model_default_iter_next),
(clutter_model_default_iter_prev): Do not instantiate a new
iterator, and update the passed one instead, as we say we do
in the documentation. This avoid leaking tons of iterators.
* clutter/clutter-model.[ch]: Update the documentation.
* tests/test-model.c: Prettify some output.
* clutter/clutter-behaviour.c:
(clutter_knot_get_type): Use the I_() macro.
* clutter/clutter-model.[ch]: Make ClutterModel and ClutterModelIter
abstract classes; also, provide more virtual functions inside the
ClutterModel vtable, to allow subclasses and language bindings to
override the entire ClutterModel using other/native data types
to store the rows.
* clutter/clutter-model-default.[ch]: ClutterModelDefault is a
default implementation of ClutterModel and ClutterModelIter using
GSequence.
* clutter/Makefile.am:
* clutter/clutter.h: Build glue for ClutterModelDefault.
* tests/test-model.c: Update for constructor changes.
* tests/test-shader.c: Fix a typo.
* clutter/clutter-model.h:
* clutter/clutter-model.c:
(clutter_model_append_value),
(clutter_model_prepend_value),
(clutter_model_insert_value): Add a _value() variant for the
insertion methods, for use of the language bindings.
(clutter_model_append),
(clutter_model_prepend),
(clutter_model_insert): Do not return a boolean: insertion should
never fail unless for a programming error, in which case we have
plenty of warnings.
* clutter/clutter-score.[ch]: Reimplement ClutterScore using
a N-ary tree to store the timelines. Remove clutter_score_add():
the same functionality can be achieved by passing a NULL
parent to clutter_score_append().
* tests/test-score.c: Update ClutterScore test unit, and add
debug printouts.
* clutter/clutter-timeline.h:
* clutter/clutter-timeline.c
(timeline_timeout_func),
(clutter_timeline_get_delta): Add a function for retrieving
the number of frames and the time (in milliseconds) elapsed
since the last timeline ::new-frame signal. This can be useful
for implementing a physics engine or just for knowing how if
and how many frames have been skipped.
Remove the layout containers: they will be moved to a
high-level library.
* clutter/clutter.h:
* clutter/Makefile.am: Remove layout and boxes from the
build.
* clutter/clutter-layout.[ch]: Remove the ClutterLayout
interface.
* clutter/clutter-box.[ch]:
* clutter/clutter-hbox.[ch]:
* clutter/clutter-vbox.[ch]: Remove ClutterBox and its
subclasses.
* clutter/clutter-label.c: Remove ClutterLayout implementation
* clutter/clutter-script-private.h:
* clutter/clutter-script-parser.c:
* clutter/clutter-script.c:
(clutter_script_parse_node): Remove special parsing for
ClutterMargin and ClutterPadding.
* clutter/clutter-types.h: Remove ClutterPadding and ClutterMargin.
* tests/Makefile.am:
* tests/test-boxes.c: Remove the boxes test case.
* clutter/clutter-effect.[ch]: Add clutter_effect_template_construct()
function, for language bindings that need to set the alpha function
but cannot call the clutter_effect_template_new() ctor themselves.
* clutter/clutter-actor.c:
(clutter_actor_real_request_coords),
(clutter_actor_request_coords),
(clutter_actor_class_init): Provide a default ::request_coords()
implementation in ClutterActor and use it to store the bounding
box passed to clutter_actor_request_coords(). This makes the code
more reliable and clean, and avoids a call to the subclass
request_coords() method if the bounding box did not change. Now,
every class overriding ClutterActor::request_coords() *must* chain
up to the parent class method or the bounding box will not be
saved inside the ClutterActor structure.
* clutter/clutter-entry.c:
* clutter/clutter-group.c:
* clutter/clutter-hbox.c:
* clutter/clutter-label.c:
* clutter/clutter-texture.c:
* clutter/clutter-vbox.c: Chain up to the parent class
request_coords() method.
* clutter/cogl/cogl.h: Add cogl_fog_set() abstracting the
glFog() functions and enabling the GL_FOG flag.
* clutter/cogl/gl/cogl.c: Add GL implementation of cogl_fog_set().
* clutter/cogl/gles/cogl.c: Add GL/ES implementation of
cogl_fog_set().
* clutter.symbols: Add new symbols.
* clutter/clutter-stage.h: Add API to enable depth cueing on
the stage using a linear GL fog, and to set the parameters
for it (#637).
* clutter/clutter-stage.c (clutter_stage_paint): Enable the
GL fog if the ClutterStage:use-fog property is true.
* tests/test-depth.c: Test the new stage API.
* clutter/clutter-label.[ch]: Fix ClutterLabel size allocation when
no bounding box has been provided, and store the box set by the
user so that it can be reused when recomputing the layout. (#600)
(clutter_label_class_init),
(clutter_label_init): Set the :wrap property default to FALSE.
* clutter/clutter-units.h: Add ClutterUnit-to-PangoUnit conversion
macro.
* tests/test-rotate.c: Fix string.
* clutter.symbols: Update
* clutter/clutter-actor.h: Rename the angle argument for
set_rotationx() to avoid gtk-doc complaining
* clutter/clutter-main.h:
* clutter/clutter-main.c:
(clutter_set_motion_events_enabled): Rename for consistency
(clutter_get_motion_events_frequency),
(clutter_set_motion_events_frequency): Add accessors for the default
motion events deliver frequency.
(clutter_do_event): Throttle down motion events delivery using the
motion events frequency setting, to avoid excessive redraws. (#608)
(clutter_context_get_default): Enable per-actor motion events, at
least for now.
* tests/test-events.c (red_button_cb):
* tests/test-grab.c (green_press_cb): Update.
* clutter/clutter-actor.[ch]: Massive API clean-ups. Initial
fixes for bugs #614 and #628.
* clutter/clutter-main.c:
* clutter/clutter-stage.c: Update internal usage of the actor
API.
* tests/test-events.c: Update test suite.
* clutter/clutter-timeline.[ch]: Add ClutterTimeline:direction
property, defining the direction (forward or backward) of the
timeline.
* tests/test-timeline.c: Test the direction property.
* clutter.symbols: Update exported symbols
* clutter/clutter-effect.h:
* clutter/clutter-effect.c:
(clutter_effect_template_new_for_duration): Add a simple constructor
for implicitly creating a ClutterTimeline with a given duration.
* clutter.symbols: Update with the new public symbols
* clutter/clutter-script.h:
* clutter/clutter-script-private.h:
* clutter/clutter-script.c:
(parse_signals), (json_object_end),
(signal_info_free), (object_info_free): Parse the "signals"
member for GObjects.
(clutter_script_connect_signals),
(clutter_script_connect_signals_full): Add new API for autoconnecting
signal handlers using the UI definition files.
* tests/test-script.c:
* tests/test-script.json: Test signal autoconnection.
* clutter/clutter-scriptable.[ch]: Rename ::set_name and ::get_name
to ::set_id and ::get_id, to avoid potential confusion with the
ClutterActor:name property.
* clutter/clutter-script.h:
* clutter/clutter-script.c (clutter_script_construct_object): Use
clutter_scriptable_set_id().
(clutter_get_script_id): Add a public function to retrieve the ID
used in the UI definition files from an object.
* clutter/clutter-actor.c: Do not set the name of the actor with
the ID set in the UI definition files.
* tests/test-script.c: Test clutter_get_script_id().
* clutter.symbols: Update with the new symbols.
* clutter/clutter-script.h:
* clutter/clutter-script.c: Add a ::get_type_from_name() virtual
function for bindings to override. The current implementation
calls g_type_from_name() and our lazy class resolver.
* clutter.symbols: Update.
* doc/reference/clutter-sections.txt: Update.
* clutter/clutter-script-private.h:
* clutter/clutter-script.h:
* clutter/clutter-script.c: Allow id-less objects: as long
as they have a "type" member, a unique id will be provided.
(json_object_end): Add merge id to the object information
structure.
(apply_behaviours), (add_children): Keep the unresolved
objects around.
(construct_stage), (clutter_script_construct_object): If an
object has unresolved children or behaviours try resolving
them when we ask for it.
(json_parse_end), (clutter_script_ensure_objects): Ensure
that the objects are fully constructed as best as we can when
finished parsing.
(object_info_free), (remove_by_merge_id):
(clutter_script_unmerge_objects): Remove objects under the
same merge id returned by the loading functions. (Fixes
bug #558)
* clutter/json/json-parser.c: Use the commodity JsonNode API
and accept bare values as root nodes.
* clutter/clutter-script-private.h:
* clutter/clutter-script.c: Unreference the created objects
only if they are top-levels, like ClutterBehaviour and
ClutterTimelines. Actors have floating references, so we
just transfer ownership to their containers, and the stage
is owned by the backend. Add the "type_func" key to the
object definition, so the user can supply its own GType
function if the class name doesn't follow the GObject rules.
Document the ClutterScript public API.
* clutter/clutter-script-private.h:
* clutter/clutter-script.h:
* clutter/clutter-script.c: Add licensing information to
the newly added files.
* clutter/clutter-script.c: Support creating behaviours with
ClutterScript. ClutterAlpha objects are implicit, but
timelines can be both explicit objects using their id or
implicit objects. Make the property resolution and translation
more robust. Support the pixbuf property.
* tests/test-script.c: Test the newly added features.
* docs/reference/clutter-docs.sgml:
* docs/reference/clutter-sections.txt: Add ClutterScript.
Initial implementation of the UI definition files. (#424)
* clutter/json/Makefile.am:
* clutter/json/*.[ch]: In-tree copy of JSON-GLib, a GLib-based
JSON parser/generator library. We use it in-tree because we might
need to change the API. Ideally, we'd depend on it.
* clutter/clutter.h:
* clutter/clutter-script-private.h:
* clutter/clutter-script.[ch]: ClutterScript, the scenegraph
generator class. It parses JSON streams in form of buffers and
files and builds the scene.
* clutter/clutter-debug.h:
* clutter/clutter-main.c: Add a "script" debug flag
* clutter/Makefile.am: Build glue.
* tests/Makefile.am:
* tests/test-script.c: Add a test case for the ClutterScript.
* configure.ac: Depend on GLib 2.14, so we can use the
g_hash_table_get_key() and g_hash_table_get_values() functions
for the time being; we can probably reimplement those, but we
are going to need 2.14 anyway if we are going to implement a
list model using GSequence.
Language bindings will have problems with raise() and lower() bein in both
ClutterContainer and ClutterActor; hence, this patch renames
clutter_container_raise() and clutter_container_lower() to
clutter_container_raise_child() and clutter_container_lower_child(),
respectively.
Since ClutterActor directly calls ClutterGroup methods we need ClutterContainer
to provide them, so that every container actor behaves the same way.
This patch makes ::raise, ::lower and ::sort_depth_order virtual functions
of the ClutterContainer interface, implemented by ClutterGroup.
The documentation has been added and deprecation warnings have been added
as well.
Finding a child by its ID is a method that should be used by every container
and not only by ClutterGroup. This is needed to actually fix the picking in
ClutterStage.
The threads_enter() and threads_leave() functions are no-ops because Clutter
is not thread-aware nor thread-safe. Leaving them in is a source of confusion
so we just remove them.
Update the NEWS and the README files with the release notes.
* clutter/clutter-behaviour-depth.c: Clarify that what drives
the movement along the Z axis is the ClutterAlpha object (we
don't have the luxury of a rollover like the opacity does);
so, if you want to go from 0 to -100 you have to use a
decreasing function, just as well if you want to go from 100
to 0. Using a min-depth of 100 and a max-depth of 0 and an
increasing function is undefined behaviour.
* tests/Makefile.am:
* tests/test-depth.c: Add a test case for the depth behaviour.
* clutter/clutter-stage.[ch]: Fix clutter_stage_set_user_resizable()
name, and add a getter for the property.
* clutter/glx/clutter-stage-glx.c: Use the accessor, not
g_object_get() to retrieve the value of the resizable property.
* clutter/clutter-behaviour.h:
* clutter/clutter-behaviour.c: Rename clutter_behaviour_clear()
to clutter_behaviour_remove_all() to avoid method clashes in
bindings.
* subclassing-ClutterActor.sgml: Add a chapter about how to
correctly subclass the actor base class.
* clutter-docs.sgml: Include the new chapter about subclassing
ClutterActor; add a description for some of the API reference
parts.
* configure.ac: If the programs required to build the manual
are not found and --enable-manual was passed, then just print
a warning and disable the manual build instead of aborting the
configure.
* doc/manual/Makefile.am: Use the full path gathered by the
configure script when invoking jw and xmlto.
* clutter/clutter-actor.c:
Fix typo in x rotation transform (Thanks to Johan Billen #138)
* configure.ac:
* doc/manual/Makefile.am:
Fix manual build and required program check.
* tests/Makefile.am:
Another typo fix.
* clutter/clutter-box.[ch]: Base class for layout containers.
* clutter/clutter-hbox.[ch]: Horizontal box actor.
* clutter/clutter-vbox.[ch]: Vertical box actor.
* clutter/clutter.h:
* clutter/Makefile.am: Build glue
* tests/Makefile.am:
* tests/test-boxes.c: Test suite for ClutterBox API and
implementations.
* clutter/clutter-container.[ch]: Add a generic actor container
interface, for actors to implement without subclassing ClutterGroup.
* clutter/clutter-group.[ch]: Make ClutterGroup implement the
ClutterContainer interface, and deprecate the colliding methods.
* clutter/clutter-layout.[ch]: Add extended layout interface.
Actors and containers requiring or honouring complex layout
management should implement this interface and provide at least
one of the available layout types: width for height, height for
width, natural size, iterative size request.
* clutter/clutter-label.c: A ClutterLabel requires height for
width layout management, so it implements the ClutterLayout
interface.
* clutter/Makefile.am: Add new files to the build.
* tests/*.c:
* examples/*.c: Update tests and examples code to use the
new ClutterContainer API instead of ClutterGroup.
This patch adds a "delay" property to the timeline object. If set,
it will delay the start of the timeline of a number of milliseconds.
If the timeline is looping, the delay will be applied just the first
time and not for every loop.
* clutter/clutter-entry.c: (clutter_entry_set_property),
(clutter_entry_get_property), (clutter_entry_class_init),
(clutter_entry_init), (clutter_entry_set_text),
(clutter_entry_set_max_length):
* clutter/clutter-entry.h:
* examples/test-entry.c: (main):
Added a max-length property whihc limits the length of the text in the
entry.
* clutter/clutter-behaviour-ellipse.c:
Remove uneeded knot signal
* clutter/clutter-behaviour-path.c:
Fix so knot signal is emitted only when a knot is reached.
* clutter/clutter-effect.c:
* clutter/clutter-effect.h:
Add a scale effect.
* configure.ac:
* doc/manual/Makefile.am:
* doc/manual/clutter-manual.xml.in:
* doc/manual/manual.xsl:
* doc/manual/style.css:
Add various bits for application developers manual.
Add a semi-private function, called clutter_base_init(), which initialises
the basic Clutter functionalities (at the moment, just the GLib type system)
without calling in the backend-specific code. This function is only useful
for gtk-doc, to introspect the library when generating documentation for
signals, properties and class hierarchy.
Also, change the documentation build system to use clutter_base_init() when
launching the scanner program.
Merge from clutter.git/master
* clutter/glx/clutter-event-glx.c:
* clutter/glx/clutter-stage-glx.c: Implement the _NET_WM_PING
protocol handling on the main stage window.
* clutter/clutter-stage.h:
* clutter/clutter-stage.c:
* clutter/clutter-main.c: Handle CLUTTER_DELETE events internally,
by calling clutter_main_quit(), and remove the ::delete-event
signal from ClutterStage; clean up the signal emission sequence
for the events: emit the ::event signal before emitting any signal
and the ::event-after signal after the signal has been emitted; move
the signal emission calls inside ClutterStage so we can call
g_signal_emit() instead of g_signal_emit_by_name(), thus sparing us
a lookup for each event.
* examples/test.c: Remove ::delete-event signal handling.
Supporting WM_PROTOCOLS allows handling the WM_DELETE_WINDOW ClientMessage,
which is then relayed to the ClutterStage actor in form of the "delete-event"
signal. Returning TRUE will block the propagation and won't close the
stage window.
Add clutter_backend_get_n_screens(), which returns the number of screens
manager by the ClutterBackend, and change clutter_backend_get_screen_number()
to return the screen number of the currently used screen; this is semantically
equivalent to clutter_glx_get_default_screen(), but leaves the door open for
a "screen" abstraction in Clutter, handled by the backend. Update the GLX
and EGL backends to retrieve and set the screen_num and n_screens members of
ClutterBackend using Xlib calls.
Add the XEMBED protocol support in the GLX backend, for embedding the
stage window into another X window. This allows cross-toolkit inclusion
and makes clutter-gtk possible.
Add the XEMBED protocol support in the GLX backend, for embedding the
stage window into another X window. This allows cross-toolkit inclusion
and makes clutter-gtk possible.
Add initial implementation of a rotate behaviour; this behaviour rotates
actors along a chosen axis, with a chosen direction, between two angles.
Missing: API documentation and the implementation for the angle boundaries
setters (double and fixed API).
GL and not GLX. Removed the get_actor_at_pos() and flush() vfuncs
from ClutterStageClass: clutter_stage_flush() becomes the private
_clutter_stage_sync_viewport() function, which should only be used
internally.
* clutter/clutter-event.c: Pop and peek the event queue
from the tail - it's a queue, not a stack.
* clutter/clutter-private.h:
* clutter/clutter-main.c: Add a boolean signal accumulator.
* clutter/clutter-stage.[ch]: Add an event argument to
the 'delete-event' signal; rename the 'input-event' signal
to 'event'; add the static scope flag to all the stage
events.
* clutter/clutter-private.h: Remove inclusion of backend-specific
headers; update the main context object; add the declarations for
the event queue functions.
* clutter/clutter-backend.[ch]: Add the abstract ClutterBackend
object, which holds backend-specific settings, the main stage,
and the event queue. Every backend must implement a subclass of
ClutterBackend and ClutterStage.
* clutter/clutter-feature.c: Protect the GLX specific calls
behing #ifdef HAVE_CLUTTER_GLX.
* clutter/clutter-actor.c:
* clutter/clutter-group.c:
* clutter/clutter-clone-texture.c: Include GL/gl.h
* clutter/clutter-event.[ch]: Update public API and implement the
event queue private API; hold a reference on the event objects;
move out the keysym-to-unicode table; add the new event types.
* clutter/clutter-color.h: Include clutter-fixed.h
* clutter/clutter-main.c: Update API; get the main stage
from the backend object; process the event received from the
queue; lock/unlock the main mutex if we have one; move the
initialisation process sooner in the init sequence, in order to
have the backend object when we check for options; call the
backed vfuncs in the pre/post parse hooks.
* clutter/clutter-stage.c: Make ClutterStage and abstract class,
implemented by the backends.
* clutter/clutter/glx/clutter-glx.h:
* clutter/clutter/glx/clutter-backend-glx.[ch]:
* clutter/clutter/glx/clutter-event-glx.c:
* clutter/clutter/glx/clutter-stage-glx.[ch]:
* clutter/clutter/glx/Makefile.am: Add the GLX backend.
* clutter/clutter/egl/clutter-backend-egl.[ch]:
* clutter/clutter/egl/clutter-event-egl.c:
* clutter/clutter/egl/clutter-stage-egl.[ch]:
* clutter/clutter/egl/Makefile.am: Add the stub for a EGL backend.
* examples/*.c: Update for the new API.
* clutter/clutter-group.h: Add public functions
clutter_group_get_n_children() and clutter_group_get_nth_child().
* clutter/clutter-behaviour.h:
* clutter/clutter-behaviour.c: Fix header alignment; fix argument
name for apidoc.
* clutter/clutter-feature.c: Use clutter_vblank_method() to
get the VBlank method name from the environment variable OR
the command line switch.
(clutter_feature_do_init): Move the check on the features
state here, to avoid an expensive function call, and inline
the function.
* clutter/clutter-fixed.c: Fix gtk-doc.
* clutter/clutter-main.c: Add a --clutter-vblank command line
switch controlling the VBlank method to be used: it overrides
the CLUTTER_VBLANK environment variable.
(pre_parse_hook), (clutter_init),
(clutter_init_with_args): Move thread initialisation before
type init, to avoid the warning that comes with newer GLib
versions.
* clutter/clutter-group.h:
* clutter/clutter-group.c: Mark clutter_group_show_all() and
clutter_group_hide_all() as deprecated.
* clutter/clutter-color.h:
* clutter/clutter-color.c: Expose clutter_color_copy()
and clutter_color_free() for the python bindings, so that
they can manager the conversion automatically; use the
slice allocator when copying/freeing a ClutterColor.
Rework part of the show/hide machinery. Allow groups sub-classes
and composite actors to override show_all/hide_all in order to
decide which children they wish to show/hide. This means that
if an actor overrides the default show/hide virtual methods, it'll
have to chain up to the parent class show/hide. While we're at it,
provide the fully recursive clutter_actor_show_all() and
clutter_actor_hide_all() methods.
* clutter/clutter-behaviour-path.c: Add apidoc for the ClutterKnot
functions; add pathological equality case for clutter_knot_equal().
* clutter/clutter-event.h:
* clutter/clutter-feature.h:
* clutter/clutter-behaviour.c:
* clutter/clutter-behaviour-scale.c:Fix parameters name so that
gtk-doc doesn't complain.
* clutter/clutter-actor.c:
* clutter/clutter-event.c: Add apidoc
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Add a clutter_actor_show_all() and a
clutter_actor_hide_all() functions; provide a mechanism for
groups and composited actors to programmatically select what to
show/hide when clutter_actor_show_all() and clutter_actor_hide_all()
are called. If you are overriding the ClutterActor::show or
the ClutterActor::hide virtual methods you should chain up with
the parent class.
* clutter/clutter-group.c: Override show_all and hide_all and
recursively show/hide every child inside the group;
clutter_group_show_all() and clutter_group_hide_all() remain as non
recursive versions of clutter_actor_show_all() and
clutter_actor_hide_all() (maybe we should rename them in order
to avoid name clashes with the bindings).
* clutter/clutter-stage.c:
* clutter/clutter-texture.c: Chain up with parent class show
and hide vfuncs.
* clutter/clutter-clone-texture.h:
* clutter/clutter-clone-texture.c: Provide API for changing the
parent texture of a clone texture actor.
* examples/behave.c:
* examples/super-oh.c:
* examples/test.c: Use clutter_actor_show_all() instead of
clutter_group_show_all().
* clutter/clutter-behaviour.h: Add a function prototype
for the foreach function: we need something more specific
than GFunc; add clutter_behaviour_get_actors(), used to
get a list of the actors.
* clutter/clutter-behaviour.c: Add debugging notes; add
a warning for behaviour implementations missing the
alpha_notify vfunc; add api documentation
* clutter/clutter-behaviour-opacity.c:
* clutter/clutter-behaviour-path.c:
* clutter/clutter-behaviour-scale.c: Reimplement the
alpha_notify functions using the new foreach function
and, where possible, by directly iterating on the
actors: this shaves off the number of recalculations
of the property/alpha values, and the number of
functions.
Avoid clutter segfaulting when used without invoking
clutter_init(). This is needed when using api documentation
tools and every other tool relying on the GObject
introspection API (esp. on a headless box). see the
note in clutter/clutter-feature.c:clutter_feature_init
for a full explanation.
* clutter/clutter-feature.c: Call clutter_feature_init()
when needed by one of the accessors of the features
structure.
* clutter/clutter-main.c:
* clutter/clutter-private.h: Remove clutter_feature_init()
public declaration: the features support check is done the
first time a feature is needed.
* clutter/clutter-main.c: Do not ever access the clutter
main context pointer directly; instead, obtain a pointer
to it via clutter_context_get_default(), which will always
return something valid.
* configure.ac: Enable debug messages also when
--enable-debug is set to "minimum".
* clutter/Makefile.am:
* clutter/clutter-debug.h: Move all debugging macros inside
this private header; make all debug macros depend on the
CLUTTER_ENABLE_DEBUG compile time define, controlled by
the --enable-debug configure switch; add G_LOG_DOMAIN define.
* clutter/clutter-main.c: Clean up the debug stuff; add
command line argument parsing using GOption; the debug
messages now are triggered like this:
CLUTTER_DEBUG=section:section:... clutter-app
or like this:
clutter-app --clutter-debug=section:section:...
where "section" is one of the sections listed in clutter-main.c,
or "all", for all sections; each section is bound to a flag,
which can be used to define a domain when adding a debug note
using the CLUTTER_NOTE() macro; the old CLUTTER_DBG() macro is
just a wrapper around that, under the CLUTTER_DEBUG_MISC domain;
CLUTTER_NOTE() is used like this:
CLUTTER_NOTE (DOMAIN, log-function);
where log function is g_printerr(), g_message(), g_warning(),
g_critical() or directly g_log() - for instance:
CLUTTER_NOTE (PANGO, g_warning ("Cache miss: %d", glyph));
will print the warning only if the "pango" flag has been
set to the CLUTTER_DEBUG envvar or passed to the --clutter-debug
command line argument.
similar to CLUTTER_SHOW_FPS, there's also the --clutter-show-fps
command line switch; also, the --display and --screen command
line switches have been added: the first overrides the DISPLAY
envvar and the second controls the X screen used by Clutter to
get the root window on the display.
* clutter/clutter-main.h:
* clutter/clutter-main.c: Add extended support for GOption
in Clutter; use clutter_init_with_args() to let Clutter
parse your own command line arguments; use instead
clutter_get_option_group() to get the GOptionGroup used by
Clutter if you want to do the parsing yourself with
g_option_context_parse(). The init sequence has been verified,
updated and moved into common functions where possible.
* clutter/pango/pangoclutter-render.c:
* clutter/*.c: Include "clutter-debug.h" where needed; use
CLUTTER_NOTE() instead of CLUTTER_DBG().
* examples/super-oh.c: Use the new clutter_init_with_args()
function, and add a --num-hands command line switch to
the SuperOH example code controlling the number of hands at
runtime.
* clutter/clutter-rectangle.h:
* clutter/clutter-rectangle.c: Add border to the ClutterRectangle
actor; add "border-width", "border-color" and "has-border"
properties, plus their accessors. The border generation code is
pretty lame, at the moment.
* examples/behave.c: Add code to test the new rectangle properties.
* clutter/Makefile.am:
* clutter/clutter.h:
* clutter/clutter-version.h.in: Auto-generated versioning macros.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Add a ClutterActor::parent-set signal,
for notificating changes of an actor's parent; add api-doc for
the actor's properties; add the ClutterActor "name" property; clean
up a bit some functions; emit the "parent-set" signal when setting
te parent and when unparenting; better warnings when lowering
and raising an actor.
* configure.ac:
* clutter/Makefile.am: Add a --enable-debug configure option,
with three levels of debugging: no, minimum and yes; default
for development releases (odd minor version) is "yes"; update
the version m4 defines; update the libtool macros: now just
changed the clutter_interface_age when releasing will update
everything else.
* clutter/clutter-behaviour-path.h:
* clutter/clutter-behaviour-path.c: Add "since" strings; add
a "knot" property which can be used to append a knot to the path;
fix apidoc.
* clutter/clutter-alpha.c: Add "since" strings.
* clutter/clutter-feature.c: Add apidoc.
* clutter/clutter-behaviour-opacity.c: Add the "opacity-start"
and "opacity-end" properties; rewrite constructor to use them.
* clutter/clutter-behaviour-path.h:
* clutter/clutter-behaviour-path.c: Add a "knot-reached" signal,
which is emitted when the path reaches a node in the nodes list;
flesh out the documentation a bit; sync the parameters names
so that gtk-doc doesn't complain about missing stuff.
* clutter/clutter-behaviour.h:
* clutter/clutter-behaviour.c: Add the alpha value to the
ClutterBehaviour::alpha_notify vfunc, so you don't have to
get the value from the alpha inside the behaviour implementations;
add more documentation.
* clutter/clutter-alpha.c: Flesh out the description.
* clutter/clutter-actor.h: Update the header.
* clutter/clutter-behaviour-opacity.c:
* clutter/clutter-behaviour-scale.c: Update docs.
* clutter/clutter-private.h:
* clutter/clutter-actor.c: Implement the defined
clutter_actor_reparent() method; call unrealize
when unparenting an actor.
* clutter/clutter-alpha.h:
* clutter/clutter-alpha.c: Add a data parameter to
the ClutterAlphaFunc; add a data+destroy parameter
to clutter_alpha_set_func() and to clutter_alpha_new(),
and turned the latter into clutter_alpha_new_full();
add a simple, empty constructor clutter_alpha_new().
These changes makes writing bindings a tad more easy,
as bindings require passing their own functions in
order to call the real alpha function.
* clutter/clutter-behaviour.h: Clean up the header.
* clutter/clutter-behaviours.[ch]:
* clutter/clutter-behaviour-opacity.[ch]:
* clutter/clutter-behaviour-path.[ch]:
* clutter/clutter-behaviour-scale.[ch]: Split the
ClutterBehaviourPath, ClutterBehaviourOpacity and
ClutterBehaviourScale into their own files as they
have been growing a bit. Fix ClutterBehaviourPath
API.
* clutter/clutter-media.h: Remove the commented
"metadata_available" signal: gtk-doc chokes up on that.
* clutter/clutter-timeline.h:
* clutter/clutter-timeline.c: Remove the useless
ClutterTimelineAlphaFunc signature; add missing accessor
methods for the properties; clean up a bit.
* clutter/clutter-util.h:
* clutter/clutter-util.c: Remove unneeded function
clutter_util_can_create_texture().
* clutter/clutter-feature.h: Sync the name of
clutter_feature_get_all() with the name declared
in clutter-feature.h.
* clutter/Makefile.am:
* clutter/clutter.h: Update.
* examples/behave.c: Update to the new ClutterAlpha
constructor.
* examples/super-oh.c: Use the right pointer and avoid
the compiler making a fuss about it.
* clutter/clutter-alpha.h:
* clutter/clutter-alpha.c: ClutterAlpha is an initially
floating object, as it makes sense only when bound to
a ClutterBehaviour; add checks for public API.
* clutter/clutter-behaviour.h:
* clutter/clutter-behaviour.c: Remove the ClutterBehaviour
constructor: ClutterBehaviour is an abstract class which
must be implemented by subclassing; add checks for public
API; unref the actors on finalize; sink the ClutterAlpha
object.
* clutter/clutter-behaviours.h: ClutterKnot is a boxed
type: add the _get_type() function declaration and the
type macro.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
(clutter_actor_class_init), (clutter_actor_set_property),
(clutter_actor_get_property): Add the "clip" and "has-clip"
properties.
(clutter_actor_set_clip), (clutter_actor_remove_clip): Emit
the notification for the changed properties.
(clutter_actor_has_clip): Simple accessor to the "has-clip"
property.
Big rework of the actor management semantics: now ClutterActor
objects behave like GtkObjects - that is they have an initial
"floating" reference that gets "sunk" when they are added to
a ClutterGroup. This makes a group responsible of de-allocating
each actor inside it, so you just have to destroy the group to
get every child actor destroyed. Also, now you can do:
clutter_group_add (group, clutter_video_texture_new ());
without having to care about reference counting and explicit
unreffing.
* clutter/clutter-private.h: Add private flags setter and
getter macros.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Clean up; inherit from GInitiallyUnowned;
add a "visible" property; add the "destroy", "show" and "hide"
signals to ClutterActorClass.
(clutter_actor_show), (clutter_actor_hide): Refactor a bit; emit
the "show" and "hide" signals.
(clutter_actor_set_property), (clutter_actor_get_property),
(clutter_actor_class_init): Implement the "visible" property; add
signals.
(clutter_actor_finalize): Do not leak the actor's name, if it is
set.
(clutter_actor_dispose): Emit the "destroy" signal here.
(clutter_actor_init): Sink the initial floating flag if needed.
(clutter_actor_destroy): Add a function to explicitely destroy
a ClutterActor.
(clutter_actor_set_parent), (clutter_actor_get_parent),
(clutter_actor_unparent): Make set_parent require a valid parent;
add unparent; check on get_parent; ref_sink the actor when
setting its parent and unref it when unsetting it. Probably we'll
need a function that does reparenting as unparent+set_parent in
a single shot.
* clutter/clutter-group.h:
* clutter/clutter-group.c (clutter_group_dispose),
(clutter_group_finalize), (clutter_group_add),
(clutter_group_remove): Make the group destroy its children when
disposing it; clean up, and use the newly-available
clutter_actor_unparent().
* clutter/clutter-stage.h:
* clutter/clutter-stage.c (clutter_stage_init): ClutterStage is
a top-level actor; clean up.
* clutter/clutter-video-texture.h:
* clutter/clutter-video-texture.c: Clean up.
* examples/super-oh.c:
* examples/test.c:
* examples/video-player.c:
* examples/test-text.c:
* examples/video-cube.c: Remove the g_object_unref() call, as the
ClutterStage object is destroyed on clutter_main_quit().
